Audio codecs
Codecs preferences on the IP Deskphone
The user cannot modify the text descriptors through the IP Deskphone; the text descriptors can only
be read by the user. After the system loads the Device Configuration file, the user preference
selections are synchronized with the system codecs specified in the Device Configuration file. This
ensures that the codecs available to the user are always set according to user preferences.
If the user modifies the order through the IP Deskphone, then the user-defined order is saved for the
codecs that are defined as system codecs in the Device Configuration file. Codecs are appended at
the end of the list in their relative order from the Device Configuration file. Until the user modifies the
order of the codecs, the list of ordered codecs reflects the order specified in the Device
Configuration file.
The following table shows examples of the list of codecs provided by Device Configuration, user
configuration, and resulting list of codecs that the system uses for presentation and codec
negotiation purposes.

Note:
The user-defined order of the codecs can be specified/changed by means of the Custom keys
file through the section [audiocodecs]. See
Deskphone downloads the Custom keys file, the IP Deskphone performs the following actions:
• The IP Deskphone parses the section [audiocodecs] from the Custom keys file. If the
codec specified within the file exists in the list of codecs in the Device Configuration file,
then the codec is added to the list of the supported codecs. Otherwise, the codec is
rejected.
• The IP Deskphone adds the last codecs, presented in the Device Configuration file, to the
list of supported codecs.
